CEGL003543 Artemisia californica - Diplacus aurantiacus Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Coastal Sagebrush - Orange Bush-monkeyflower Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association occurs in the Santa Monica Mountains region of California on moderately steep to steep southwest- to northeast-facing slopes at low elevations between 160 and 467 m. It is characterized by a codominance of Artemisia californica and Diplacus aurantiacus in the shrub layer. Although no individual species are strongly characteristic in the herbaceous layer, the native perennial grasses Melica imperfecta and Leymus condensatus occur in about half of the samples. The emergent tree layer is generally absent.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Traditionally in the shrublands with a codominance of Artemisia californica and other species (Eriogonum fasciculatum, Salvia leucophylla, etc.), California ecologists have used mixed alliance names based on the codominant species (e.g., Gordon and White 1994). This is the first case when a codominant Artemisia californica - Diplacus aurantiacus association has been described, so we have decided not to describe it as a new alliance but simply as an association within the broader view of the Artemisia californica alliance. The proliferation of mixed alliances based on codominance is a philosophical dilemma that will continue to plague ecologists in California for some time to come.

Physiognomy and Structure: No Data Available
Floristics: It is characterized by a codominance of Artemisia californica and Diplacus aurantiacus (= Mimulus aurantiacus) in the shrub layer. Although no individual species are strongly characteristic in the herbaceous layer, the native perennial grasses Melica imperfecta and Leymus condensatus occur in about half of the samples. The emergent tree layer is generally absent.
